I beleive that this is a tricky area just like bikes; different people have different likes. I used to be a only Michelin person but since have tried the Bridgestone 002's on my T and so far have loved them, have a set of 003's waiting for my Duc. Mind that I do not go into tracks anymore, all street riding (still very agressive as permited by surroundings) and have heard and read opinions about the Bridgestones that slide controlably when they get very hot and pushed hard but is understandable for a road/track tire.
The cost/performance point of view is the best above the others IMHO for the street. If I were to track my bike, I would use DOT's with the compound for the track and conditions with tire warmers and trailered. Thats me though, I feel that if you're going to do something, do it right.
I consider road/track tires to be more on the street side and to be the best they can in that environment and for an occasional track day at an intermediate level at the most. Just MHO, as also I would see wrong doing to put a DOT on the street for all it's intended purposes.
